摘要:
2-dimensional carbon thin films are described, as well as their processes of preparation, and their specific uses. The 2-dimensional carbon thin films are fabricated by preparing an organic polymeric thin film precursor, which is then subjected to a carbonisation process to remove at least some of the non-carbon atoms. Using the disclosed process, 2-dimensional carbon thin films having improved dimensional characteristics can be reliably prepared, which presents clear advantages in applications which have until now been restricted to the use of 2-dimensional carbon thin films having less useful dimensions.
